The side walls 243 c and 243 d, formed by ribs 240 e, are very important, vertically arranged, “thin plate” shaped, static aerofoils formed by ribs 240. These aerofoil sides serve four key purposes, namely: 1) to join the top and bottom walls 243 a and 243 b physically into a rigid lightweight structure; 2) to bend the surrounding air flow around the large frontal area of housing 220 without “separation”, eliminating nearly all form drag possibilities from the structure, thereby greatly reducing the possible wind stress on the tower 210; 3) to create via this bending of the surrounding air flow, a high speed low pressure flow regime directly behind the housing 220 tending to suck the air flow through the housing 220 past the blades 224 and directly negating one of the prime assumptions of Mr. 1. The opposite end of arm 62, along with the lower end of link 32, are pivotally connected to an end segment 34 a extending from the end of blade 20 which segment may be an extension of, or coincidentally concentric with, shaft 34 which extension extends into pit 55 through a vertical access slot 55 a formed in the pit wall adjacent to the bearing block 26 a.

Connected to each inlet 122 a is a siphon pipe 126 consisting of a flared intake section 126 a, an elbow section 126 b and a straight penstock section 126 c connected in series. In accordance with the invention, the angular position of flap 68 is actively controlled in relation to the crank cycle of crank arm 38 and thus the angular position of blade 20 on its shaft 24. More particularly, flap 20 can be swung between a first position wherein its trailing end, constituting the trailing end 20 b of blade 20 as a whole, is angled toward the TDC position of the blade and a second position wherein the trailing end of the flap is angled toward the BDC position of the blade.
Since the Magnus rollers start out at zero angular velocity at their TDC and BDC positions during each half cycle, there is always a portion of the cycle where this force is zero or slightly negative, but fortunately this can be arranged, by careful attention to gear ratio and roller diameter design details, to be during that part of the cycle when the blade output torque is getting its maximum boost from the powerful Wind/Water Hammer effect, which is also the portion of the cycle when the drag force itself is making its maximum positive output torque contribution. 20. The two blades 406 oscillate 180° out of phase in their respective passages with the Magnus rollers contributing blade “lift” as described above, aided by the aforesaid boundary interactions at TDC and BDC. Thus the self-energized Magnus rollers 356 render the otherwise geometrically symmetrical blades cyclically aerodynamically non-symmetrical. In this embodiment, the very inertia of the mass of the Magnus rotor also performs the dual function as the flywheel in the articulated vane version of the apparatus.

16. Moreover, each blade 370 also includes an imbedded Magnus roller 374 in body 372 a which is rotated in correlation with the swinging motion of the blades to increase the blade lift at the side of the blade facing the corresponding TDC or BDC position toward which the blade is moving at any given time.

The chamber 74 b volumes on opposite sides of piston 74 a are connected by pipes 76 a and 76 b, respectively, to the two fluid channels of a spring biased, two position solenoid, fluid or mechanically-operated valve 78 which may be part of a module 80 preferably contained within main body 66. Those two channels of valve 78 are also connected to a pair of pipes 80 a and 80 b. In order to initiate the flow of water through housing 122, the pump 142 is activated and each valve 138 is switched so that the pump pulls a vacuum at each vent tube 136. Dolor de espalda cancer pancreas . This draws water into the siphon pipes 126 to initiate the siphoning of water so that water flows down to the flow channels 124 a and 124 b in housing 122, after which valves 138 may be switched to the closed position. Thus, valve 78 can deliver fluid under pressure to and vent it from pipes 76 a and 76 b, respectively, depending upon the position of the valve.

This feathers flap 68 to a progressively greater degree which, in turn, reduces the lift, the Venturi and Water Hammer forces of blade 20 resulting in less power being produced by the apparatus. FIGS. 20A and 20B show the housing 220′ in greater detail. Mounted to each outlet 122 b of housing 122 is a draft pipe 134 consisting of an elbow section 134 a connected to the corresponding outlet 122 b and a flared discharge section 134 b connected to elbow section 134 a which discharges the flow beneath the level of the water on the downstream side of the dam. As noted previously, for maximum power, the flow exit from housing 122 as well as the power converter 152 should be near the level of the water W on the downstream side of the dam D. Also for maximum efficiency, the draft tubes 134 should be designed to recover the siphon-velocity energy at the outlet end of housing 122 converting it into negative gage pressure down to the approximate vapor pressure of water.
